Today I opened the Victron app on my iPhone 8 and got a message to update the software, which I did so successfully. Then when I attempted to connect to my 100/15 Smartsolar I got a second message to update the firmware. I did so but got stuck at 66%. I attempted to quit but got the message not to do so, so I didn't. Then I got a 'firmware update failed' message. Since then, no lights, no connecting, no recognizing the smartsolar unit. Nothing. Appears to be bricked. Is there a way to reset the firmware? Hoping for a fix as I rely on my panels and the controller to keep my batteries topped off during winter layup.
